Ah, macaroni and cheese. It's like the pizza of the pasta kingdom — think of any combination of ingredients, throw them together with cheese, bake for a while, and invariably you end up with something delicious. Want to keep it simple and stick with the old-fashioned, no-frills classic? You can do that, and it will be delicious. Want to add bacon? Of course you do. Lobster? A entire garden's harvest? Have ityour way. Whether you like your mac 'n' cheese with beef and bacon or you're a lactose-intolerant vegan, one thing we can all agree on is that there's a mac 'n' cheese out there for you, and it will be delicious. That's why we want to know: Who makes the best mac 'n' cheese in America? We expect regional differences to duke it out for the crown. We will be surprised if the winner doesn't have breadcrumbs on top. (Who doesn't love breadcrumbs?) As we've done for burritos and pizza and burgers, we'll put the life-changers to a vote.
